If you have an unlocked bootloader and can boot into it, does it not recognize your phone or simply not allow you to run commands? My download mode reads as DISABLED in my bootloader and I can run fastboot commands. I think you're a little confused on terminology, too. You'd sideload software via ADB with TWRP or for an OTA, your stock recovery. You'd fastboot flash partitions via the bootloader.

I can boot into fast boot mode by hardware button combo pressed but its not recognising any fast boot or ADB commands when I connect it on my laptop
When connected by USB and in your bootloader, run 'fastboot devices' and if it doesn't show your serial # then it isn't recognizing your phone, likely a driver issue.

Do not try to do that. We have a lot of bricked devices (Including Mine) after we tried rolling back to Marshmallow. Just a warning. If you still want to take a risk, go ahead by all means.
Driver issue....resolved.....Working now!!...Thank you

No problem. I would listen to Indian84 and stay on Nougat until you can flash full factory images.

Hello. Just got my a7 today and I am glad to say that I have Verizon and my phone is perfect. But I tried the unlock bootloader adb sideload that requires b20. It fails. Also trying the update from b18 to b20 didn't work either.
So am I able to root from b29? What should I do or where should I look for answers?
Thanks

A new bootimage is only needed if you want to root B29 without unlocking the bootloader.
Use tenfar's tool to flash only TWRP recovery, flash the modified fastboot I linked, fastboot oem unlock, flash SuperSU 2.65.

I am still unclear regarding precise steps needed to unlock my bootloader. And ZTE took down the previous method request for improvement I think I read...

Problem is I am stuck on 1. I installed the Quallcomm drivers and wwlan as instructed, however, my windows doesnt display any comm devices and nothing from Qualcomm. So I am unable to backup my phone onto my computer, which is priority no.1.
** clarification ... I feel more comfortable using linux but the tools are windows so I am dual booting into windows. I might be missing a simple step regarding my phone device manager....

Your phone has to be in edl mode to see it as a comm on windows. adb reboot edl
I used the b27 to install twrp with axon7root.exe then used twrp unlock bootloader but couldn't fastboot on windows had to switch to linux.
Careful about rooting and unlocking bootloaders if you can't even follow really detailed instructions!

So, for those of us whonhave not yet taken "the plunge", do you mind detailing the exact steps that finally worked for you? These multiple threads have a variety of trials, errors & successes..TIA
I play pokemon go so do not want to root the phone.. unless there is a way to hide the root from the app.
Hello,
Guys I've been reading for hours (feels like I'm running in circles) lol
I just got the Axon 7 and I'm not able to figure out how to get it fully working with Verizon, And I'm not getting any help from ZTE or Verizon.
Can anyone point me in the right direction?
I'm to the point where I'm ready to send it back.

Stick your active Verizon SIM into Slot 1, turn on A7, enable Data Roaming on Slot 1, manually set APN (if desired), done.

Magisk Root = Systemless root enabling bootloader and system hide so safetynet api cannot view that information

Good evening,
I have trying to get my phone working for a few weeks now to no avail. I can access fastboot mode and it recognizes the device but I cannot access recovery mode. The phone is stuck on the logo screen, powered by Android. When I try to boot to recovery mode, it stays on the logo screen. Any advice? I am willing to try anything at this point.
Thank you!
Sent from my A0001 using Tapatalk
When you seeing the dead Android you push and hold power button and press volume+ additionally?
We actually do not have a recovery partition. You want to flash it to your current boot slot.
Do this:
fastboot getvar current-slot
this will return your <letter>
then do
fastboot flash boot_<letter> <filename>.img
You can continue forward.
good luck.

To clarify, I assume that the letter will be the partition, a or b. What do you refer to with filename? Is that the zip file with the image to flash? Apologies if the answers are obvious. Just learning over here. Thanks again.

That may or may not be possible.
The first thing I do is fully unlock my bootloader.
For tother people I suggest enabling the OEM Unlock option.
That doesn't me you have to unlock, but it just might save you.
For the OP, did you select the option to OEM Unlock?
Recovering from a boot loop with a locked bootloader might be a challenge.

Hi,
I’ve got an older Verizon LG V20 that’s been bricked. I hid it in a drawer for the past year or so, and stumbled across it again. If I can get this fixed, I’d love to update it and give it as a gift to an older friend who has a 6 yr old crap android phone. But first, some history…
-bought used in great shape and rooted with Dirty Santa to run on TMobile. I don't recall which ROM I used, but it was very stock minus the carrier apps. My wife had a chance to go to Italy, so we bought a 3rd party european SIM with 30 days of data and voice from Three UK. Short story is that the phone never recognized the SIM, but she used it to take some great pics during her stay.
-once back in the US, I decided to try a different ROM and I think I flashed the wrong files or something… it’s my fault but I honestly can’t recall if I loaded a Samsung image instead, or what exactly happened.
Currently, the phone boots ONLY into fastboot mode. ADB does not recognize the device, and I’m thinking that I’ve lost TWRP Recovery since I can’t enter Recovery Mode at all.
If I do hold Vol Down + Power, I get a Hard Reset menu, but nothing in there helps.
I tried using LGUP, but the device is "not recognized."
I’m at a loss as to what to do at this point. If there IS a way to un-brick this, I think it would make a great phone for a good friend.
If anyone has any suggestions, I’d love any ideas that you may have. I tried looking to see if any other threads cover this, but I’m not seeing anything with specifics or pointers to How-Tos. If I missed the relevant links, I’d appreciate being pointed to them.
Also…
-if I can return to Stock condition, I can then unlock the bootloader and flash a more current ROM again. Would I need to pick a new radio so it better matches TMobile vs the Verizon setup it originally came with?
thanks for reading!

When I run fastboot in Terminal, I get a blank response-- that is, a simple carraige return with no info listed.
This is on a fresh Win10 install with the latest Platform Tools package (Justt adb & fastboot) from the Android Studio website.
Are there other drivers that I need? When I installed LGUP, I did install the LGMobileDriver_WHQL_Ver_4.1.1.exe installer as well.

Win 7 update
Ok, I've installed WIN7, Android Platform Tools (just ADB & Fastboot), LG drivers and LGUP.
Now when I do the fastboot command, I get a true response:
fastboot devices
VS995aa11a111 fastboot (where a=letters, 1=numbers)
YAY!
So at this point, if I load a TWRP.zip, would I be able to boot into Recovery, instead of fastboot mode?
I checked the official TWRP website, and the latest is TWRP 3.2.3-0.
EDIT: I looked in the LG Section, and it appears that there is not an official TWRP for the LG V20. Is that right?
Having gotten to the point where the laptop recognizes the phone, I really don't want to make a dumb mistake :silly:
thanks for getting me this far!

Hi
I'm just a noob but I am interested in the problem you are having and am following it to see what comes up with it.
There is a good fastboot thread here:
https://forum.xda-developers.com/showthread.php?t=2277112
On the first page you have options to wipe before flashing - i.e. system, boot, data, RECOVERY etc,
Maybe give those pages a read while waiting for someone more knowledgeable to fix your phone...
Since you are not sure what happened maybe the modem was affected which I think is bad...
I think doing a "fastboot getvar all" might give you a status of what you are dealing with .... since it gives you versions
of things...
Anyhow, good luck reviving the phone - "rooting" for you haha!

secondhand2,
THX for the links! Those were very helpful!
No need to call yourself a noob... I think I outrank you in that department at this point!
I did try your suggestion of fastboot getvar all, and found something interesting...
when I did the command it returned (bootloader) unlocked:no
which I thought was WEIRD, since the phone -was- unlocked with a custom ROM before I messed things up.
I have attached a screenshot to this msg with the full info report.
So now I'm wondering if that's why my previous attempt at flashing TWRP failed?
Does this mean I have a soft-brick or a hard-bricked phone at this point?
I"m learning more through everyone's help and input, but I'm still lost as to where to go from here.
Hi,
I have a US996 and I unlocked it using the lg web site - they send a bin file that you can use to unlock the phone.
There are different exploits on different versions of V20 phones. THere are also versions of Nougat that have an anti rollback that stop you from going from a recent OTA update back to an older one that can be exploited to get root. For example, on the US996 I have., if I had bought it and it had been patched with 10p (not 100% sure which version was the cutoff point) even if the phone was unlocked, I might not be able to get root. So the versions of the ROMs/firmware are imnportant. As it happened I had the 10f version so rooting was possible - but I followed the threads on this site for my specific phone and stuck to STOCK rom's.
So I'm not sure about what ROM you have - i..e which version of the vs995 is rootable after you unlock the phone. And the unlocking method to use - I'm not familiar with dirty santa or lafsploit (might not have spelled that correctly). There is a tool called LGUP and a good thread on that below that I was reading but it is long read which is good for learning.
I can only point you to some threads - but unlocking is the next hurdle.
You might also want to use the latest TWRP and Magisk if you do get to root the phone. I used PHOENIX591's TWRP
- there is a good thread on that. https://forum.xda-developers.com/v2...-t3720239/post78529520?nocache=1#post78529520
Sorry I can't help you more with this - you do need to get the phone unlocked first. Some of these things are very device specific
I'm still keeping an interested eye on this...
Here is the other thread

I can only point you to some threads - but unlocking is the next hurdle.
You might also want to use the latest TWRP and Magisk if you do get to root the phone. I used PHOENIX591's TWRP
- there is a good thread on that. https://forum.xda-developers.com/v2...-t3720239/post78529520?nocache=1#post78529520
Sorry I can't help you more with this - you do need to get the phone unlocked first. Some of these things are very device specific
I'm still keeping an interested eye on this...
Here is the other thread

Good Luck!

You're incorrect arb hasn't been incremented on the 996

Hi cnjax
The thread I used discussed arb but from what I remember it was never clear how to know which arb ( 0 or 1 ) a particular update was at. Are you saying there is never an increment for the us996?
Thank you for clarifying

Hi cnjax
It is a bit difficult to read everything n get a clear picture sometimes. I'm hoping you would clarify something
If TWRP is not installed and the phone is unlocked but not rooted which method could be used to install oreo 20f?
Would you be forced to install 10f (nougat) to root and install twrp first before moving on to oreo?
In this scenario I assumed nougat was on the phone originally and it seems the phone is locked from the fastboot info given...but let's say it gets unlocked
Is there a method to install oreo first instead of starting with nougat and version 10f? If there is that would be awesome
Thank you!

If his bootloader is locked he'll need to downgrade, root and unlock the bootloader with dirty santa, flash updated twrp, flash a rom and magisk

Post #71 about dumping contents/partitions with lgup seems a good idea -
Then I would try fastboot oem unlock to see what happens but not sure if that can break the bootloader or not. I think you would be in a deeper hole if it went south on you. I'm not sure if doing fastboot oem unlock can be risky at this point
